Mobile Broadband (or Wireless Wide Area
Network) Networks
A Mobile Broadband network, also known as a Wireless Wide Area Network
(WWAN), is a high-speed digital cellular network that provides Internet
access over a much wider geographical area than a WLAN, which typically
covers only from 100 to 1000 feet.
Your computer can maintain Mobile Broadband network access as long as the
computer is within a cellular-data coverage zone. Contact your service
provider for coverage details.
NOTE:
Even if you are able to make a call from your cellular phone in a specific
geographical location, that location may not necessarily be within a cellular-data
coverage zone.
